2 answers:

7 0

In projective geometry, any pair of lines always intersects at some point, but parallel lines do not intersect in the real plane. The line at infinity is added to the real plane. ... In the projective plane, the two opposite directions of a line meet each other at a point on the line at infinity.

It gets cut off but it says ' Write the number marked with an arrow on the number line below as an improper (top-heavy) fraction

Anit [1.1K]

Answer:

1.2

Step-by-step explanation:

it's 1.2 because

the marked parts on the number line represent a fraction of the whole

so in writing this

it will be decimals

and wen the marked lines between 0 and 1 are counted it is 4

so starting each marked line represent 2

0.2,0.4,0.6,0.8,1,1.2,1.4,......

so from 1 the next marked part is 1.2

so the answer is 1.2
